A. W. CASH STRAINER June 10 1924.
Filed Aug. 2. 1920 IN VENTOR WITNESSES Mam/k w w-k4 Patented June 10, 1924.
UNITED STATES PATENT OFFICE.
ARTHUR W. CASH, OF DECATUR, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO A. W. CASH COMPANY, A CORPORATION OF DELAWARE.
STRAINER.
Application filed August 2, 1920. Serial No. 400,795.
To all whom it may concern:
Be it known that I, ARTHUR W. CAsH, a
, citizen of the United States, residing in the city of Decatur, county of Macon, and State of Illinois, have invented a new and useful Improvement in Strainers, of which the following is a specification.
My invention relates more particularly to a class of devices commonly used on pipes or conduits to separate the flow of fluids therethrou h from foreign substances, and commonly hnown as strainers.
One object of the invention is to provide a device that will effectively separate and retain foreign substances quite commonly entrained in fluids such as scale, cuttings, grit and fibrous particles of material sometimes used in making up joints in the pipes or conduits. The construction of the strainer element being such that the flow of fluids therethrough will separate and deposit the foreign substance into a lower adjoining sediment chamber without ordinarily clog ing the strainer element, and thereby impe ing or restrictin the fluid flow.
Another 0 ject is to provide a device that while being very effective, is yet simple and i inexpensive in manufacture and constructed in such manner as will readily permit of emptying the sediment chamber when it becomes filled, or ready removal and cleansing of the strainer element whenever clogged by abnormal quantities of fibrous or other clinging foreign matter, or when worn from long continued service.
Accomplishment of the objects set forth is shown in the construction embodied in the accompanying drawings in which, Fig. 1, is a central vertical section through a strainer having an inlet pipe or conduit connection at 2, and outlet pipe or conduit connection at 3.
Fig. 2 is a horizontal section on line AA through central upper chambered portion of the strainer looking downward.
Reference letters and figures refer to similar parts throughout the drawings and specifications.
In Fig. l, fluid enters inlet end 2, into chamber 4, thence dividing, a portion flows downward through curved passage way 5, while the other portion flows upward through curved passage way 6, both fluid streams again uniting in the central chamber 7, of screen member 8, which entirely surrounds central chamber 7.
Inlet chamber i, and connecting dependent sediment chamber 10, are separated from outlet chamber 9, by the two parallel walls 15 and 16, and their curved connecting Wall 17, walls 15 and 16, having apertures to re ceive and retain cylindrical shaped screen member 8.
From central chamber 7, of screen member 8, the fluid must all pass through the meshes to enter and flow from the outlet chamber 9, and on through outlet connection at 3. During the flow of fluid, all foreign matter that is too large to pass through the meshes of the screen member 8, will fall below into sediment chamber 10, if of greater specific gravity than the fluid, while foreign matter of less specific gravity than the fluid and which may be retained within cylindrical shaped screen 8, will be churned in the vortex of the two uniting streams until worn to such size or condition that it will pass through the meshes of the screen 8.
A looped. Wire member having parallel tion of body casing in such manner that screen member 8, is retained as against further upward movement. The lower looped portion 12 of the wire member resting within the cup shaped inner end of screw threaded plug 14. effectually prevents downward movement of screen 8, which is, thercfore, retained in its correct operative position. 1When it is desired to remove the screen member 8, for cleaning or renewal, it is accomplished by removal of screw threaded plug 14, thus permitting withdrawal of wire supporting member with screen member 8, attached to the parallel sides 1111, thereof, It may readily be seen that when screw threaded plug 14 is removed for Withdrawal of screen member 8, that sediment chamber 10, may at the same time be readily freed from any deposit of foreign matter before replacement of screen member 8, and screw threaded plug
